Initial import from the monolithic Qt.
This is the beginning of revision history for this module. If you want to look at revision history older than this, please refer to the Qt Git wiki for how to use Git history grafting. At the time of writing, this wiki is located here: http://qt.gitorious.org/qt/pages/GitIntroductionWithQt If you have already performed the grafting and you don't see any history beyond this commit, try running "git log" with the "--follow" argument. Branched from the monolithic repo, Qt master branch, at commit 896db169ea224deb96c59ce8af800d019de63f12

+ markers as per bug
+ <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=581"

+ <li> libtiff/tif_print.c: added (untested) support for printing
+ SSHORT, SLONG and SRATIONAL fields.
+
+ <li> libtiff/tif_fax3.c: Avoid reading CCITT compression options
+ if compression type mismatches. See

+ store single SampleFormat value for multisampled images. See
+ <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=562">
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=562</a>.
+
+ <li> libtiff/tif_write.c: Allow in-place updating of the compressed
+ images (don't work properly with all codecs). For details see GDAL bug
+ <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=534">
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=534</a>.
+
+ <li> libtiff/tif_jpeg.c: Workaround for wrong sampling factors used
+ in the Intergarph JPEG compressed TIFF images as per bug:
+ <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=532">
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=532</a>.
+
+ <li> libtiff/tif_open.c: Use dummy mmap/munmap functions in
+ TIFFClientOpen() when the appropriate client functions was not
+ supplied by user.
+
+ <li> libtiff/tif_dirread.c: Fixed problem with handling TIFF_UNDEFINED
+ tag type in TIFFFetchNormalTag() as per bug
+ <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=508"
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=508</a>.
+
+ <li> libtiff/tif_codec.c: Fixed typo in TIFFInitPackBits name as per:
+ <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=494">
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=494</a>.
+
+ <li> libtiff/tif_fax3.c: Fixed problem, introdiced in 3.6.1 release,
+ with the CCITT encoding modes as per bug
+ <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=483">
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=483</a>.
+ We need more work on fax codec to support update mode.
+
+ <li> libtiff/tiff.h: Fixed tag definitions for TIFFTAG_YCLIPPATHUNITS
+ and TIFFTAG_INDEXED as per bug
+ <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=475">
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=475</a>.
+
+ <li> libtiff/{tif_win32.c, tif_unix.c}: Check whether the pointer is
+ NULL before proceeding further as per bug
+ <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=474">
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=474</a>.

+ http://bugzilla.remotesensing.org/show_bug.cgi?id=468</a>.
+
+ <li> libtiff/tif_dirwrite.c: Fixed handling of writable ASCII tags
+ that are field_passcount=TRUE properly. Arguably anonymous custom
+ tags should be declared as passcount=FALSE, but I don't want to change
+ that without a careful review.
+
+ <li> libtiff/tif_write.c: Fixed reporting size of the buffer in case
+ of stripped image in TIFFWriteBufferSetup(). As per bug
+ <a href="http://bugzilla.remotesensing.org/show_bug.cgi?id=460">
+ http://bugzilla.remotesensing.org/show_bug.cgi?id=460</a>.
+

+ patch from Gerben Koopmans.
+
+ <li> libtiff/tif_dirread.c: Check field_passcount value before setting
+ the value of undefined type, patch from Gerben Koopmans.
+
+ <li> libtiff/{tiff.h, tif_fax3.c}:Fixes for AMD 64 platform as
+ suggested by Jeremy C. Reed.
